Here's the full setup and tests I've done.
I sync with a Yahoo account. Both this and (now) iCloud are set up in Settings/Accounts to have Contacts On (on iphone 8 and ipad mini 4, latest IoS).
On Contacts/ Groups both Yahoo and iCloud are displayed - both are ticked.
Yahoo contacts used to have First and Last names (on the Basic version) but the new (?when? - recently since Verizon takeover?) version only has Name.
On iPhone and iPad most Contacts have 2 ‘linked contacts’, Yahoo and iCloud. I went through and laboriously set all contacts to use the iCloud for the ‘unified contact display’ on both devices. This fixes the display to show in last name order with first name shown too (not bold) for those with 2 links.
Ones that (I think) I created on iPhone do not show any linked contacts, but they have been/ are replicated on Yahoo after a few minutes (?after exiting and reloading on Yahoo and iPhone?), with last name appended to Yahoo Name (so it contains
first, last), and first name on iPhone showing Yahoo Name, and last name cleared. They still do not show any linked contacts.
None of the iPhone-entered contacts get replicated to iPad (and so changes don't get applied either).
New iPad entries do get replicated to iPhone, but not Yahoo.
Some tests I did:
- Create contact on iPhone – first and last name. Replicated to Yahoo, both names in Name, iPhone version auto-changed to have Yahoo Name in first name only, surname cleared. Not replicated to iPad. No ‘linked contacts’ shown.
- Create contact on iPad – first and last name. Replicated to iPhone, first and last name, not replicated to Yahoo. No ‘linked contacts’ shown.
- Create contact on Yahoo – first and last name (used old Basic version of Yahoo software). First and last concatenated automatically when viewed through newer Yahoo software, replicated to iPhone with copy of Yahoo Name in first name, no
last name. Not replicated to iPad. No ‘linked contacts’ shown.
I’d like iPhone-entered contacts to replicate to iPad (and Yahoo) but not get subsequently messed up by Yahoo. iPad-entered contacts to replicate to iPhone as now (and Yahoo). Yahoo-entered contacts to get replicated to iPhone and iPad, where I
can subsequently change Name to first and last name and have that displayed on iPhone and iPad, and not get messed up by Yahoo later.
Any ideas (and thanks for reading this long spiel 😊)?
